PowerPoint presentations are often criticized for the excessive use of text on the slides. In a study of 97 academic scholars, we found that presenters indeed used substantially more text than is advised. Speaking anxiety was found to be related to the time spent on preparing and rehearsing, and time spent on rehearsing is related to the number of words on the slides. Anxious presenters appear to use PowerPoint slides as speaking notes. Presenters should be trained to overcome their speaking anxiety by means other than the abundant use of words on their slides.

PowerPoint has received much criticism regarding excessive use of text and the lack of contact with the audience. Why presenters use PowerPoint in this way has not been studied so far. Our study using interviews with beginning and advanced presenters shows that some use the program as a speaking note and as a means to draw the attention away from themselves. Some even think that PowerPoint can replace rhetorical skills. Slides are mainly designed on the basis of commonsense, instead of guidelines based on human information processing. Implications for the teaching of PowerPoint use in business communication are discussed.
